Bethenny Frankel Wears Red String Bikini, Flaunts Cleavage

Bethenny Frankel may be going through a "brutal, brutal time," as she very candidly shared on Nightline on Tuesday, Aug. 13, but the reality star's amazing body is showing no signs of stress. The Skinnygirl mogul was photographed the same day on Miami Beach rocking a tiny two-piece and looking like a walking ad for her low-cal alcoholic beverages -- that is, skinny and sexy!

The 42-year-old mom to daughter Bryn, 3, (with soon-to-be ex-husband Jason Hoppy) looked comfortable in her curves as she played in the surf and showed off her taut body in a red string bikini. After taking a dip, she covered up in a cute white crocheted dress and a wide-brimmed straw hat. Frankel is in town to promote her book Skinnygirl Solutions and her upcoming talk show.

On Tuesday night's interview, the star talked about what it was like to go through the breakup of her marriage while millions watched along. "I felt like I disappointed people, because I felt like I was this role model, that represented the fairy tale," Frankel explained. "I'm definitely bruised."

"I would imagine eventually, sex would be a nice release, but you know, who knows," she continued. (Last month, Frankel vacationed in St. Tropez with hedge-fund Warren Lichtensten, but a source told Us Weeklythey are just friends.) "If I'm exercising or doing yoga it'll take the edge off on some level. And then I like to have a Skinnygirl cocktail. I'm not going to lie. Honestly. It's mommy juice."
